TX2-family module with the highest TTP temperature rating

Asked as: “We're retrofitting an old TX2-based rugged box for a hotter environment. Which TX2-family module has the highest TTP temperature rating?”

Answered by the Rapidflare agent

Jetson TX2i has the highest TTP rating in the TX2 family, at 85 °C. The standard Jetson TX2 is rated 80 °C. developer... +1developer.nvidia.com ↗“thermal.max_ttp_temp_c=85 °C”developer.nvidia.com ↗“thermal.max_ttp_temp_c=80 °C”

What this means for your retrofit:

  • Same connector: The TX2i uses the same 400-pin B2B (50x87mm) form factor as the TX2 and TX2 4GB. It's described as an industrial/rugged module with "extended temp/vibration" support and 8GB LPDDR4 ECC memory. developer...developer.nvidia.com ↗“8GB LPDDR4 ECC, extended temp/vibration”
  • Power and heat: The TX2i's power envelope is 10–20 W, compared with 7.5–15 W for the TX2. Check that your box's power supply and cooling can handle that before swapping it in. developer... +1developer.nvidia.com ↗“power.power_envelope=10-20 W”developer.nvidia.com ↗“power.power_envelope=7.5-15 W”
  • TX2 NX: Its 90 °C figure is a junction-temperature limit, not a TTP rating, so you can't compare it with the TTP numbers above. It also uses a different connector (260-pin SO-DIMM).
  • TTP is not ambient temperature: TTP is the module's thermal limit, not the hottest environment the box can run in. The real ambient limit depends on your enclosure and how heat gets from the module's thermal plate out of the box.
  • Lifecycle: The Jetson TX2 and TX2 4GB are listed as EOL. The TX2i's lifecycle status is not listed in the catalog. developer...developer.nvidia.com ↗“identity.lifecycle_status=EOL”
